Request InfoAltechnaThe PowerXP is a compact version of Altechna’s motorized attenuator. This device attenuates a free-space laser beam (or pulse) continuously without introducing additional energy fluctuations. Contrast better than 3000:1 (Tp:Ts) is achieved, since this attenuator is mounted with a high-contrast polarizer. This very compact attenuator version can be easily integrated into custom optical systems.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2022 IssueLaser Power MeterThe LabMax Touch Pro laser power meter from Coherent Inc. makes data acquisition and analysis for nW continuous wave lasers up to multi-kW, pulsed industrial lasers easy to access through an...Photonics Showcase May 2022 IssueDYAD Dual-Beam Laser ModuleThis is a fiber-coupled module featuring an operational beam and an optical red aiming beam.
